Hydroxycarbonate precursors with different Cu/Zn/Co/Cr atomic ratios and CuZnCoCr oxides obtained by thermal treatment of the precursors at different temperatures (623, 723, and 973 K in air) have been examined. Characterization has been per

Here, we report on a size-controlled synthesis of highly crystalline germanium particles, via the self-sustained reaction of GeO2 with Zn, Mg, and NaBH4. The thermodynamic analysis suggests that the GeO2 + 2Zn and GeO2 + NaBH4 systems are characteriz
